REFRIGERATOR.

Specicaton of Letters Patent.

Patented Dec. 29, 1914i.

Application led Fehruary'z, 1910, Serial No. 546,476.

To all whom it' may concern Be it known that i, WILLIAM voN BAUM BaC1-r, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification, reference being had to the accompanying drawing, `forming a part thereof.

The main objects of this invention are to provide a refrigerator with a lining molded or formed in one piece of some suitable composition or material, which can be easily kept clean and which will avoid waste of ice; to provide for the support of the ice boX or receptacle within the refrigerator independently of the lining; and generally to simplify and improve the construction and efficiency andV convenience of refrigerators.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and defined in the claims.

l'n theaccompanying drawing like characters designate the same parts in the several iigures.

i Figure l is a vertical section from front to rear on the line l l, Fig. 2, of a refrigerator embodying the invention; Fig. 2 is a horizontal section onvthe line Q 2, Fig. l; and Fig. 3 is a transverse vertical section on the line 3 3, Fig. l of the upper part of the refrigerator.

The refrigerator comprises an outer casing a having a door frame formed with one or more doorways or openings in front, a one-piece or jointless molded lining c which is open in front next to the door frame., and an ice box or receptacle (Z extending from the door frame by which it is supported independently of the lining into the upper part of the refrigerator, a clear vertical air circulating space loeing left between the back and sides of said box or receptacle and the lining.

In the present case the refrigerator is shown as having two doorways or openings, one above the other, the doors, which may be of the usual or any suitable construction being omitted. The doorways or openings are formed, as shown in Figs. 1 and 2, with continuous rabbets or seats for the doors. The lining c, which is of smaller dimensions than the casing a, is supported within the casing at a distance therefrom so as to form an insulating space e at the top, bottom, back and sides, by rabbeted corner blocks or strips f. It is secured in place to the door frame so as to form and maintain a tight joint 'therewith by one or more binders which may consist of U-shaped rods g passing around the back and sides of the lining and threaded at the ends which pass through the door frame and are adjustably fastened therein by nuts 7L. By this means the lining may be drawn and held tightly against the door frame and ingress of air into the refrigerator chamber and consequent waste of ice are prevented.

The lining, which may be made of any suitable plastic material such for example, as a composition of asbestos, sawdust and magnesite, is molded in one piece with the internal corners and angles coved or rounded to avoid fracture along the lines of the angles and to facilitate keeping the interior of the refrigerator clean. The lining may also be molded in the rear vertical angles with lugs z' for supporting racks or shelves at the back without perforating or marring the lining, hooks j being provided on the door frame for supporting the racks or shelves' in front.

The ice box or receptacle Z which may be convenientlvmade as shown, with the back and sides of wood covered with sheet metal to give it the desired strength and stability, is open on the front side next to the doorways or opening into which it is fitted` and through which it is removable. It is formed or provided at its front or open side with a flange or projection fitting into and adapted to bear inwardly against the rabbet or seat in the door frame Z). It is also formed or provided on the bottom adjacent to its front or open side with a depending shoulder or projection d adapted to bear outwardly against the door frame 7) below the upper door opening. The outwardly bearing shoulder or projection rl and the inwardly. bearing flange or projection above mentioned, cooperate with the door frame to support the ice receptacle in operative position within the refrigerator independently of the lining c, with a clear air circulating space between them at the sides and back. The flange for supporting the ice box or receptacle from the door frame may be provided by riveting or otherwise fastening an angle iron frame 7c to the front edges of said box or receptacle around the opening is depressed and slopes downward toward the back, where it has a short discharge spout loosely fitting into a removable drain tube m. It is formed with an opening a` around which it is upwardly fianged to permit Vfree circulation of air between the ice receptacle and the storage compartment below. A removable downwardly and rearwardly inclined corrugated tray 0 resting on the ledges Z, prevents the water or melting ice from dripping through said opening. Upon the raised front and rear portions of this tray rests a removable rack p which supports the ice.

The ice boX or receptacle is easily removed from the refrigerator by tipping the angle iron frame 7a forward till it clears the upper part of the door frame and the discharge spout is withdrawn from the upper end of the drain tube m, as indicated by dotted lines yin Fig. l,` then lifting it a short distance until the shoulder or abutment d', the depressed bottom and the short discharge snout of the receptacle will clear the upper door sill when it may be withdrawn through the doory opening, the width of the ice box being slightly less than the width of the door opening, as shown in Fig. 2, and the sides of the ice boX being of "considerably less height than the door opening, as shown inFig. l. rlhe remm able drain tube m is loosely fitted in'v'ertically alined openings in the casing a and lining c so that it can be readily withdrawn therefrom and can be tipped or moved laterally at its upper end which is unconfined except by the short discharge spout of the ice receptacle Z when it is in its normal position, as shown by full lines in Fig. l. The ice receptacle fits loosely over the upwardly proiecting inner portion of the upper door sill'which may be chamfered or beveled on the inner side, as shownin Fig. 1, to permit said receptacle to Vbe tipped forward thereon, as indicated by dotted lines. By thus constructing and supporting the ice `box or receptacle independently of the lining, it may not only be readily removed from and replaced in the refrigerator, but it may also be securely held in place without fastening it or supports therefor, to the lining and thereby perforating, marring or otherwise injuring the same. The bottom of the lining may be formed as shown in Fig. 1, with a forwardly projecting ledge e7 fitting into a rabkbet or recess in the lower door sill.

Theice box may if desired, be permanently fastened to the door frame, but'it is preferably left unattached and removable, as shown and hereinbefore described.

Various modifications in 4the details of construction and arrangement of parts may be made Hwithout departing from the principle and scope of the invention.

' lf claim: y

l. ln a refrigerator the combination of a casing having a door frame and opening on one side, and an ice receptacle removable through said opening and having projections on the upper and lower front parts thereof, adapted to bear respectively inward and outward against the door frame and to support said receptacle within the refrigerator independently and clear of the casing at the sides and baclr.

ln a refrigerator the combination of a casing having a door frame and opening on one side, ailining inclosecl in said casingV and openen the side next to the door frame, and an open front ice receptacle removable through the door opening and provided att the frontl with a vertically disposed flanged frame removably fitting in the door opening and adapted to bear inwardlyy against thel door frame, said receptacle being also prol vided with a transverse shoulder dependingfrom the bottom thereof and adapted to bear outwardly against the door frame below the door opening and to cooperate with said flanged frame to support said receptacle independently of the lining with a clear space between them iat' the sides and back. y n y 3.' ln a refrigerator theV combination of a casing having a door frame, a lininginclosed in said casing and open on-the side next to said frame,and a removable open front ice receptacle having projections on the upper and lower front parts thereof adapted to bearrespectively inward and outward against the door frame and to support v,said -receptacle independently of the lining with a clear air circulating space between them at the sides and back. y
